Preparing the final delicious dish would take around only few hours!, lets start ...

Step 1: Ingredients First

4 large skinned chicken breasts
2 large red chillies as required, I know some ppl dont like that spicy
4 cloves of garlic, finely chopped
150ml double cream
150ml natural yogurt
1 fresh lemon
1 tsp Garam Masala (more than chilly powder)
2 tsp Ground Cumin
2 tblsp Coriander leaves
50g Butter
1/2 tsp salt
1.5kg fresh ripe tomatos if available

Step 2: Lets Cook

Core and de-seed the chillies, chop them up fine as shown on image

Step 3: Next

Add the chillies, fine chopped garlic, cumin and garam masala to a small bowl.

Step 4: Mash It Up

Mash it up and then add the juice of the lemon, coriander leaves and the yogurt to create the marinade. Really this should be blended but as I don't have a blender I did it by hand. If you have a blender though, use it.

Step 5: Choping

Chop up the chicken into 3cm pieces and put into a non metallic bowl

Step 6: Mixing

Mix in the marinade with the chicken, cover and put in the fridge for at least 3 hours

Step 7: Side by Side

While freeze is doing his work .... quarter the tomatos and put into a pan with nothing else. Warm for 20mins on a low to medium heat

Step 8: Straining

Strain the tomatos into a clean pan using a fine sieve. Throw away the skins and pulp left over.

Step 9: Tomato Sauce!

You end up with a tomato sauce like so, heat this for 50 mins until reduced to a nice thick sauce. You may need to skim off any yellow stuff off the top as it is heating.
